Page 9: Usage
When you put a magnet that has enough magnetic power close to the module, the switch is closed .Then the SIG pin out put a high voltage. You can use this to control the led. Grove As the picture on the below indicates, the Magnetic switch is connected to digital port 9 of the - Basic Shield and the LED is connected to digital port 13. - Page 10 void loop() if(isNearMagnet())//if the magnetic switch is near the magnet? turnOnLED(); else turnOffLED(); void pinsInit() pinMode(MAGNECTIC_SWITCH, INPUT); pinMode(LED,OUTPUT); /*If the magnetic switch is near the magnet, it will return ture, */ /*otherwise it will return false boolean isNearMagnet() int sensorValue = digitalRead(MAGNECTIC_SWITCH); if(sensorValue == HIGH)//if the sensor value is HIGH? return true;//yes,return ture else...
